Shrub rose plant named Korades

ABSTRACT

A shrub rose having a vigorous, well-branched and upright habit of growth; dark green, glossy, disease-resistant foliage and attractive pink flowers; and being easily propagated from softwood cuttings.

The present invention relates to a new and distinct variety of roseplant of the shrub class which was originated by me by crossing thevariety KORmarie with an unnamed seedling.

The primary objective of this breeding was to produce a new rose varietyhaving the shrub-like characteristics and healthy foliage of KORmariecombined with the very healthy foliage of the unnamed seedling. Flowercolor could be anything between the yellow-pink flowers of KORmarie andthe red of the unnamed seedling. The objective was substantiallyachieved, along with other desirable improvements, as evidenced by thefollowing unique combination of characteristics that are outstanding inthe new variety and that distinguish it from its parents, as well asfrom all other varieties of which I am aware:

1. A vigorous, upright, well-branched growth habit;

2. Dark green, glossy and healthy foliage;

3. Dark pink, lightly scented flowers; and

4. Ease of propagation from softwood cuttings.

Asexual reproduction of this new variety by softwood cuttings, asperformed at Wasco, Calif., and Sparrieshoop, Germany, shows that theforegoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
